TRANSOM ADJUSTER.

.Application filed July, 9, 1925. Serial No. 42,348.

This invention relates to building construction and has particularreference to de vices for operating transoms or similar structures. j i

Among the Ob ectsoftlns lnventlon is to provide mechanism to facilltatethe operation of a transom or the like and whereby,

said transom may be readily locked shut or opened to any desired extentby the operator from some point of vantage.

Another object of this invention is to pro vide generally a novel powertransmission device, and particularly one which is applicable for use inconnection with tran soms or other movable objects, and whereby theoperation of said transom may be 'ac- (jOll'lPllSllBCl from a pointremoved therefrom according to the convenience of the operator.

Still another object of this invention is to provide in conjunction witha movable object such as a transom or the like mechanism comprising alock which is arranged for retaining said transom in a fixed or lockedposition and means co.-operating with said lock in a novel manner andwhereby said transom may be opened or closed as desired. 1

lVith the foregoing and other objects in View the invention consists inthe arrange ment and combination of parts hereinafter described andclaimed, and while the invention is not restricted to the exact detailsof construction disclosed or suggested herein, still for the purpose ofillustrating a prac tical embodiment thereof reference is had to theaccompanying drawings in which like reference characters designate thesame parts in the several views, and in which Figure 1 is a perspectiveview showing a typical use of my invention in connection with a transomwhich is in open position.

Fig. 2 is a front elevation of the same but with the transom in closedposition.

Fig. 3 is a section on the line 33 of Fig. 2.

Fig. 4: is a section on the line 4.--4 of Fig. 3.

Fig. 5 is a section on the line 5-5 of Fig. 8.

Referring now more particularly to the drawings, I show my invention asused in connection with a movable or pivoted structure such as a door ortransom comprising a sash 10 arranged to be received in a frame 11 abovea door 12. Means is provided for retaining said transom in adjusted orlocked position such as a lock 13. Preferably said lock is secured tosaid sash, and has suitable co-operation with a member such as a strike14: which is mounted upon the frame 11. The sash is mounted for openingand closing as desired and is preferably hinged to said frame by meansof the hinges 15. The lock mechanism may therefore be arranged to haveengagement with its strike when said sash istilted from one position toanother as when the transom is closed. For this purpose the lock isprovided with a movable bolt 16 which is actuated by a spring 17 so asto engage the strike automatically. The bolt may be pivoted upon a pin18, upon which likewise the spring may be secured as by means of a coil19 formed upon the pin and whereby the free portion of the spring abutsagainst the lock casing and thus exerts a force upon the bolt tend- .ingto throw the same toward the left, the strike being formed in the shapeof a hook or catch to readily engage the same.

Means are provided whereby the transom may be operated from any pointmost convenient to the operator, said means comprising one or moreflexible members such as the ropes 20 and 21 whereof the former isarranged for use in closing the transom while the latter is used foropening the same. As stated hereinbefore, I contemplate generally meanswhereby the transom may be fixed for any desired adjustment or tiltedposition as to vary the flow of air therethrough or for any otherpurpose as desired. and for the sake of simplicity, I have found it mostconvenient to secure this object by providing means such as a lockingdevice 01 friction brace 22 which is operable in con junction with theflexible members aforesaid. Said friction brace is a Well knowntelescopic device which is pivotally mounted for easy and eflicientco-operation with the transom.

The rope 20 has co-operation with a stationary object such as the frame11 as by means of an anti-friction member such as the pulley 23 wherebythe direction of power transmission by means of the rope may be changedin a convenient manner. More specifically, the rope 20 after passingvertically upward and then horizontally over said pulley to a pointadjacent to the strike has engagement with another antifri-ction deviceand then with the sash in such manner that a downward force apwiththepulley 23 the rope may extend sub stan-tial'l-yparallel thereto in aneat and efficient manner. The rope then passes rearwardly behind thepulley 26 and then forwardly into engagement with the sash, the

pulley 26 being arranged to. take up the forceexerted along the rope inclosing the transom. Thus said rope may be secured to a member such as alug 27 formed upon the lock casing and generally to anyrelativelystationary member or part whereby the sash may be moved. Therope is passed through a hole in the lug and is then formed with a knot28, the lug being offset inwardly toward the frame. 11 to provideclearance between the bolt 16 and: said knot.

Means is provided for opening the tran som in conjunction with the rope21, and for disengaging the bolt from its strike should the transom belocked. Thus the rope. 21 may be secured to. the bolt as within the hole29 thereof, a knot 30: being provid'cd to retain.- the same inengagement, the rope entering the look through. the side of the casing.As a neat and preferred arrangement, I provide a pivoted member suchas abell crank 31 m oanted uponthe sash with one arm of which the verticalportion of the flexible member 21 has engagement while with the, otherarm of which a horizontal portion of said member has co-operation fortransmitting a force exerted at the knob 32 for tilting the bolt inclockwise direction to open the'lock. By continuing the pull upon saidknob, thetransom will be opened against the resistance of the frie tie-nbrace 22 and final-lyleft in any open.

extending along. said construction whereby' the sash may be operatedfrom a distance, said flexible means comprising a. plurality of flexiblemembers one ofwhich extends: along the frame and substantially parallelto the surface thereof, and a pair ofpulleys. recessed in said frame,one of which takes, the direct pull tending to actuate the sash towardsaid frame, thev other pulley being positioned forwardly of the. firstmentioned pulley and acting as a guide for said flexible member from theother pulley and to bring the member to the surface of the frame.

In testimony whereof I my signature.
